The type of atrial fibrillation that you have depends on how often atrial fibrillation occurs and how it responds to treatment.

Paroxysmal AFib are episodes of AFib that occur occasionally and usually stop spontaneously . Episodes can last a few seconds, hours or a few days before stopping and returning to normal sinus rhythm, which is the heart’s normal rhythm. Some people may have single episodes of AFib.

Diagnosis – Atrial Fibrillation. The diagnosis of atrial fibrillation is confirmed with a standard 12-lead ECG. P waves are absent, coarse “fibrillatory waves” can frequently be seen and sometimes no atrial activity can be identified. The QRS complexes are “irregularly irregular”, with varying R-R intervals.

In comparison with Sinus rhythm, AF has no P wave as the SA node is not functioning. However, the atria generate up to 600 stimuli/min and each stimuli is picked up by the ECG machine.
